STEERING-WHEEL FOR PLOWS.

v Specification of Letters Patent.

Application filed August 9, 1912. Serial N 0. 714,291.

To alt 'w/mm it may concern Be it known that I. Janus H. LIILLER, acitizen of the United States, residing at Geneseo, in the county of Riceand State of Kansas, have invented a new and useful i SteeringQWheel forPlows of which the fol lowing is aspecificatioi'i.

The present invention appcrtains to steering mechanisms, and aims toprovide a novel and improved means for controlling the steering wheel ofa wheel mounted plow.

In the accompanying drawings Figure l is a fragmental side elevation ofthe wheel mounted plow embodying the present in vention. Fig. 2 is aplan view thereof, portions being broken. away, and the plow bei ingremoved. 7 Referring specifically to the drawings, the number 3designates a rectangular plow frame, which is carried by suitable groundwheels, and which is equipped with a In carrying out the presentinvention,- a fork 5 has its shank or stem journaled through the tongue4, and a steering wheel 7 is journaled betwen the arms of the fork toengage the soil in advance of the plow. A brace 8 is se lied to thetongue 4t and the shank 6 of the fork to more effectively hold the forkin proper position, the lower end of the brace loosely embracing theshank ,spertive flexible elements will be result, the strain transmittedto of the fork to permit the fork to rotate freely. A lever 9 isattached at an intermediate point to the upper end of the shank 6,directly above the tongue 4, and has its ends projecting laterallyrelative to the tongue. To the ends of the lever 9 are attached draftrods 10, which extend rearwardly over the forward end of the frame 3,and which have short chains or flexible elements 11 attached to theirrear ends. The chains 11 are trained over the pulleys or on a crosspiece 13 carried by the intermediate portion of the rame 3, and theother ends of the chains 11 are secured to treadles l4 fulcrumed to thecross piece 13 directly below the respective pulleys. The treadlesproject rearwardly from the cross piece 13 andare arranged in advance ofa suitable operators seat. 15 carried by the rear end of the frame, inorder i that the operator may place his feet upon I thetreadles to swingthe same. I

Innse, the operator may readily swing the steering wheel by depressingone or the other of the treadles, the position of the steering wheelbeing determined by the position at which the treadles are held by thefeet of the operator. It will be observed that when the treadles arereleased, the steering wheel may run idle, the steering wheel preferablybeing of the caster type. Particular attention is directed to the factthat when the respective treadles are swung downwardly, those portiorisof the flexible elements between the pulleys and treadles will move toand from the fulcrums of the treadles. In this man ner when one treadleis depressed the recarried toward the fulcrum of the treadle, and as athe treadle will be directed practically on a line passing through thefulcrum of the treadle. Consequently, the steering wheel may be held toone side or the other by the respective treadles, in a highly efiicientmanner. I f one of the treadles is depressed and swung forwardlysufiiciently, the respective flexible element 11 will be locked over thefulcrum of the treadle, so that the steering wheel may be mostefficiently held toward the side to which it is turned, there beinglittle tendency to swing the treadle back to normal position due to thesteering wheel engaging the soil.

What is claimed is:

In combination with a wheel frame, a front by, a pair of rotary guidescarried by the frame, a pair of treadles fulcrumed to the frame directlybelow the respective guides, and flexible members connecting therespective treadles and steering wheel and passing over the guides, thefree ends of the treadles mounted projecting rearwardly so that when therespective treadles are swung, those portions of the flexible membersbetween the guides and treadles will move to and from the fulcrums ofthe treadles. I

In testimony that I claim the foregoing as my own. I have hereto affixedmy signature in the presence of two witnesses.
